When you add a BWSplitView to a window and then set the max size
for a subview(s) and then start dragging the divider around, the
divider works as expected except if say you set the max size for
the left splitview and put an element in the right splitview that
auto resizes in it's view then in the running app you drag the
mouse in the splitview and it hits the left pane max size the mouse
will continue moving right, and the subview in the right splitview
subview will continue resizing a little bit and then stop.

It appears to only happen the first time you do this, subsequent
attempts don't appear to do the same thing. The left view does not
appear to continue resizing when this happens, but the right
subview does (in the case of the app I designed where just the left
subview in the splitview has a max size.)

I've recorded a video of this happening and will update this
report with said video link (if necessary) showing this bug in
action when I get to a less restrictive network.
